Hi Chad, recently I came across one guy who has similar situation like you. And we find out that it’s due to the battery. We change 2 x 18650 power battery and this problem solved. I think my be the battery is not offering enough power to fire the atomizer. As you has said. The smok xcube II reads the ohm so it won’t be the shortage or open circuit. Hope this can solve your problem too.

HI Chad, I checked your email address and found no order history on http://www.3fvape.com
Would you pleas tell me the firmware version of your xcube II, I will try to help but I can’t promise I can solve this problem.
